Mining mobile equipment communication system based on optical fiber automatic releasing and recovering apparatus

Abstract

The invention discloses a mining mobile equipment communication system based on an optical fiber automatic releasing and recovering apparatus. The mining mobile equipment communication system comprises a control main box body, wherein the control main box body comprises an anti-explosion shell and a shell cover plate; an explosion-suppression horn mouth is formed in the side face of the anti-explosion shell; the optical fiber automatic releasing and recovering apparatus is arranged on the shell cover plate; the optical fiber automatic releasing and recovering apparatus comprises an optical fiber reel; an optical fiber reel end cover is arranged on the top of the optical fiber reel; an optical fiber wire-outlet hole is formed in the side face of the optical fiber reel; a wire-winding apparatus is arranged in a wire spool in the optical fiber reel; a wire spool cavity is formed in the middle of the wire spool; a wire spool optical fiber hole is formed in the side face of the wire spool cavity; a one-way clutch is arranged at the bottom of the wire spool; the one-way clutch is connected with a driving system; a wire spool supporting frame is arranged on the top of the wire spool; the lower end of an optical fiber sliding ring is connected with the wire spool supporting frame through an optical fiber fixing bracket; and the upper end of the optical fiber sliding ring passes through the optical fiber through hole in the optical fiber reel end cover. By adoption of the optical fiber automatic releasing and recovering apparatus, the automatic releasing and recovering of the optical fibers is realized, so that the underground communication quality of the mining mobile equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of underground communication in coal mines, in particular to a mining mobile device communication system based on an optical fiber automatic retractable device. Background technique [0002] With the advancement of science and technology, the degree of mechanization and automation of coal mines continues to increase, and the status of communication technology in coal mine production is becoming more and more important. necessary means. Coal mine communication system is developing towards a comprehensive information network integrating video, image and data transmission "three in one". However, due to the constraints of communication equipment technology and special environmental conditions, underground communication in coal mines still has many problems. Due to the poor underground environment, severe humidity and dust, and metal components such as railways, pipes, brackets, and cables are arranged in the ...

Problems solved by technology

Because mining mobile equipment needs to meet the necessary explosion-proof requirements, its mass is too large, and long-distance optical fibers also have considerable weight. Especially small mining mobile equipment, it is difficult to have enough power to drag the optical fiber

Even if the mining mobile equipment has enough power to pull the optical fiber, during the pulling process, the optical fiber will bear a huge pulling force and the friction generated by contact with the ground, which will easily cause fiber breakage and damage, affecting the normal communication of the equipment

The general optical fiber release device can only release the optical fiber autonomously, and the optical fiber needs to be recovered artificially, which not only wastes manpower, but also when the mining mobile equipment is backed up, if the optical fiber cannot be manually lifted or recovered in time, the mining mobile equipment is easy to crush on fiber optics, causing fiber optic damage
